After an unusually short overhaul and paint job, ERPX's B&O Q4b #4450 looked like she just arrived from the B&O shops. However, ERPX's owner, Mr. Renzulli, is a rather quirky guy and does not want to fire her up until a special guest, Mr. Long of MRLX, arrives at Pittsburgh. Mr. Renzulli will be mounting the MRLX 3-chime on 4450 for her first trip and Mr. Long will ride in the cab. She was transported to the roundhouse by CNJ GP7 #1527, which can be seen behind 4450. After her first run, 4450 will get the B&O 3-chime owned by Mr. Renzulli and the MRLX 3-chime will go to B&O T3c #5594. B&O Q4b 2-8-2 #4450 CNJ GP7 #1527
